Acupuncture may be a viable way to treat substance abuse, according to doctors.

Advocates say each needle can help reduce stress and depression associated with addiction.

Acupuncturists and naturopathic doctors in New Hampshire say the treatment should be available nationwide.

They say recovery programs should have the flexibility to decide how and when to use ear acupuncture.

The news comes as Purdue Pharma, the company best known for selling the prescription painkiller OxyContin, announced it would stop marketing opioid drugs to doctors.

The move allegedly comes after a series of lawsuits that blame the company for contributing to the opioid epidemic.
